<p>Dermatosis papulosa nigra (DPN) is a superficial, black or brown benign papule that develops mainly in dark-skinned individuals over the face and neck. Clinically seborrheic keratosis shows a stuck-on appearance that differentiates it from DPN. Histopathological examination described that both were identical. Many types of lasers are used as treatments for it. Traditional surgical procedures such as curettage, electrosurgery, and snip/shave excision are still considered as a therapeutic modality. Although electrodessication (ED) is a simple procedure, studies on ED use for DPN with a good number of cases are lacking. This paper presents the evaluation safety, efficacy and cost-effectiveness of ED for the treatment of DPN in Fitzpatrick’s skin type IV to VI. A total of 40 patients (11 male and 29 female) with DPN over the face and neck with skin type IV–VI were included. Superficial ED (monopolar, low, 2–3.5 W) was done by just touching the lesion under topical anesthesia. All preoperative photographs as well as 2-, 4- and 8-week post-procedure photographs were examined by two independent dermatologists who had no prior information concerning the procedure, (both known hereafter as “blinded observer”): one for examining efficacy in terms of poor improvement (0%–25%), fair (26%–50%), good (51%–75%), or excellent (76%–100%), by counting completely cleared lesions; and the other for examining side effects in terms of hypo/hyperpigmentation and scarring. As a result, 85% of patients showed excellent improvement (&gt;75% clearance), 7.5% good (51%–75% clearance), 5% fair (26%–50% clearance) and 2% poor (0–25% clearance) as measured by the “blinded” observer. Post-inflammatory hyperpigmentation was observed in 15% cases, whereas hypo-pigmentation was documented in 7.5% cases. Only in two cases (5%) was lesional scarring noted. Those complications were cleared after eight weeks. In this study, ED was observed to be an effective, well-tolerated and cost-effective method for treatment of DPN in colored skin. Complications were few, and therapy was performed appropriately with effective postoperative measures.</p>

Introduction: forensic science involves diverse scientific disciplines that apply their particular expertise to the legal and judicial system. However, in the last decades this science has been linked to humanitarian actions and human rights proceedings. Forensic dentistry plays a vital role in personal identification. The lip print analysis is a relatively a simple procedure used in this discipline. It consists of patterns evaluation of cracks in the elevations and depressions on the labial mucosa. The aim of this study was to determine the lip print patterns of a southern Colombian population in order to add evidence of preconditions for forensic issues as part of a humanitarian forensic action. Methods: a total of 384 participants ≥ 35 years old were included in this study. The lip prints were analyzed through Suzuki and Tsuchihashi’s classification in order to identify the predominant lip prints in males and females. Descriptive analysis was used to determine the sample characteristics and a χ2 test was performed to analyze independence according to sex variable for these categorical data. Results: the analyses showed that Type I and I’ together were the most commonly lip prints seen in this sample, followed by Type II. There were not statistical differences between males and females. Conclusions: the evaluation of lip prints is a cost-effective method, and it could be an alternative in developing countries, especially in those that address massive violations of human rights.

Objectives: Investigating cytopathological characteristics of thyroid swellingsby fine-needle aspiration cytology (FNAC) compared to histopathological examination. StudyDesign: Observational study. Place and Duration: Department of Pathology in collaborationwith Department of Surgery, Liaquat University of Medical and Health Sciences from November2014 to December 2016. Methods: A sample of 100 FNAC specimens was selected as perinclusion and exclusion criteria. FNAC procedure was conducted by technique of “to andfro movements” of needle for thyroid nodules of <1.5 cm size from central part of swelling.Peripheral part was aspirated in cases of large thyroid swellings. Smears were air dried andstained with May–Grunwald Giemsa (MGG) and H & E stain for histopathological examinationby microscopy. Data was analyzed on SPSS 22.0 at 95% confidence interval (p≤0.05). Results:Mean± SD age was noted as 47.6±8.6 years. Of total 200 cases, male and female were 90 (45%)& 110 (55%) respectively. Benign thyroid lesions were noted in 140 (70%), malignant thyroidlesions in 50 (25%) and 10 (5%) proved indeterminate thyroid lesions. FNAC shows sensitivityof 89%, specificity 97% and accuracy of 91%. Conclusion: FNAC is an easy, time escaping,cost- effective, simple procedure and valid technique for the triage of thyroid swellings.

Dermaroller is a novel therapeutic modality in dermatology. Through physical trauma from needle penetration, dermaroller induces a wound healing cascade with mild temporary damage to the epidermis. This allows for the enhancement in the absorption of topical therapies across the thick stratum corneum. Dermaroller has become increasingly utilized over the last several years as it is a relatively simple procedure that is cost effective, well tolerated and offers cosmetic and therapeutic benefits. The ability to treat localized areas of disease made it popular in acne scars, alopecia, striae, melasma, actinic keratoses. The procedure has few adverse sequelae compared to other therapies, is highly effective and a viable resurfacing option for color of skin.

Background: Fine needle aspiration cytology in orbital lesions gained importance in the last 3 decades. FNAC can be used for aiding the clinician to plan treatment of orbital and eyelid tumors study was undertaken to evaluate the role of FNAC as a diagnostic tool for diagnosis and management of various orbital and eyelid lesions, as it is of great value in the diagnosis of new primary, recurrent and metastatic orbital tumors.Methods: Patients of different age groups presenting with orbital and eyelid lesions were studied over a period of 4 years from March 2013 to Feb 2017. The 75 patients selected for this study were clinically evaluated and then investigated with computed tomograpghy (CT) scanning. Each patient was subjected to FNAC under direct vision/ultrasongraphy guidance with sterile 22 guage needle without anaesthesia. Biopsy was done to confirm the cytological diagnosis.Results: The age of patients varied from 3 years to 70 years. On cytology 61 cases were benign and 14 malignant. Histopathological examination of 53 cases was done which confirmed the cytological diagnosis.Conclusions: FNAC is a useful, rapid, safe and cost effective method for diagnosing orbital and eyelid pathology.

Accidental injury to anterior region with fractured and mobile teeth can be an awful experience to young female patient. Treating such patient requires knowledge judgment and skill of the operator. In the present case report multiple horizontal root fracture in cervical third region with mobile undetached crown was successfully stabilized by a very simple procedure using hedstrome endodontic file as an endodontic implant. In a two year follow-up period the tooth was completely asymptomatic clinically as well as radiographically. Immobilization of fractured root by endodontic instrument with MTA considered to be a simple ,reliable and cost effective method to save a tooth that would have been difficult to restore with good long term prognosis. Key-words: Incisors, Horizontal Root Fractures, H File


The choice of cost-effective method of anticorrosive protection of steel structures is an urgent and time consuming task, considering the significant number of protection ways, differing from each other in the complex of technological, physical, chemical and economic characteristics. To reduce the complexity of solving this problem, the author proposes a computational tool that can be considered as a subsystem of computer-aided design and used at the stage of variant and detailed design of steel structures. As a criterion of the effectiveness of the anti-corrosion protection method, the cost of the protective coating during the service life is accepted. The analysis of existing methods of steel protection against corrosion is performed, the possibility of their use for the protection of the most common steel structures is established, as well as the estimated period of effective operation of the coating. The developed computational tool makes it possible to choose the best method of protection of steel structures against corrosion, taking into account the operating conditions of the protected structure and the possibility of using a protective coating.

About one hundred and fifty wastewater reservoirs store effluents for irrigation in Israel. Effluent qualities differ according to the inflowing wastewater quality, the degree of pretreatment and the operational parameters. Certain aspects of water quality like concentration of organic matter, suspended solids and chlorophyll are significantly correlated with the water column transparency and colour. Accordingly optical images of the reservoirs obtained from the SPOT satellite demonstrate pronounced differences correlated with the water quality. The analysis of satellite multispectral images is based on a theoretical model. The model calculates, using the radiation transfer equation, the volume reflectance of the water body. Satellite images of 99 reservoirs were analyzed in the chromacity space in order to classify them according to water quality. Principal Component Analysis backed by the theoretical model increases the method sensitivity. Further elaboration of this approach will lead to the establishment of a time and cost effective method for the routine monitoring of these hypertrophic wastewater reservoirs.
